Description
Technical Field
The invention belongs to the technical field of feed and feed additives, and particularly relates to a production method for preparing rumen bypass series products.
Background
The cultivation of ruminants is an important component of the animal husbandry in China, and the ruminants are special in physiological structure layout and have four stomachs, namely a rumen, a reticulum, a omasum and a abomasum. Each stomach has a unique function, wherein rumen is a place for microbial fermentation, and all ingested feed is fermented by microbes in rumen, i.e. is subjected to microbial pre-digestion, so that nutrients necessary for part of animals are utilized or degraded by the microbes, and thus the inherent physiological functions of the animals are lost. Such as lysine, methionine, choline chloride, glucose, ammonium chloride, urea, etc. The ruminant is different from a monogastric animal, and the selection of a high-quality ruminant feed additive has great significance in the processes of digestion, metabolism, growth, propagation and the like of the ruminant, so that rumen-bypass series products are hot points of research in recent years, and the most promising products are currently applied as coating products. The product is designed by utilizing the difference of pH value physiological conditions of different digestion parts of the ruminant, is stable in a rumen environment with the pH value of about 5.4, and can be absorbed and utilized by the animal by virtue of the action of digestive enzymes of small intestine under the condition of the pH value of 2.4 after reaching the true stomach. The rumen bypass rate is more than 90 percent, and the small intestine release rate is 100 percent. The coated products on the market at present are mainly coated with amino acid, the general steps are that auxiliary materials are added on the basis of amino acid raw materials for granulation and then coating, and the rumen-bypass amino acid product has the defects that only part of the rumen-bypass amino acid product is stable in the stomach, the release of the amino acid after rumen bypass is less, the apparent biological value (rumen bypass rate X small intestine release rate) of methionine is low, and the granules are not uniform. Therefore, a method for coating with good effect and uniform particles is urgently needed in the field.
Disclosure of Invention
In view of the above problems in the prior art, the applicant of the present invention provides a method for producing rumen bypass products. The product prepared by the invention is spherical particles with uniform granularity, high purity and good quality.
The technical scheme of the invention is as follows:
the rumen bypass product comprises the following raw material components in parts by weight:
the core-spun material is at least one of amino acid, choline chloride, urea, ammonium chloride or glucose.
The binder is one or more of dextrin, polyvinyl alcohol, carboxymethyl cellulose, vinyl acetate resin or acrylic resin.
The surfactant is one or more of polysorbate, sodium dodecyl benzene sulfonate, stearic acid, tween 80, alkyl glucoside APG, fatty glyceride or fatty sorbitan.
The amino acids include lysine and at least one of methionine, cystine or cysteine.
A production method of a rumen bypass product comprises the following specific steps:
step 1, auxiliary material pretreatment: heating and melting palm oil in a reaction kettle, controlling the temperature while stirring until the palm oil is uniformly stirred, adding a surfactant after the temperature is stable, and uniformly mixing for later use;
step 2, preparing master batches from raw materials: adding the crushed and sieved raw materials into white carbon black and a binder, and granulating and rounding;
step 3, bottom spraying operation: and (3) putting the dried master batch in the step (2) into a fluidized bed coating machine, starting a fan, and spraying the mixture of the palm oil and the surfactant in the step (1) onto the master batch in the step (2) at a constant speed through a spray gun to finally obtain a finished product.
The stirring temperature in step 1 is 80-90 ℃.
And step 2, after the crushing pretreatment, sieving the powder with a sieve mesh number of 80-160 meshes.
In the step 3, the temperature in the fluidized bed is about 35-45 ℃, the flow rate of the palm oil is 30-50 r/min, and the hot air temperature of the spray gun is above 140 ℃ and 150 ℃. Sieving the product with 40-80 mesh sieve.
The beneficial technical effects of the invention are as follows:
the invention aims to provide a production process for preparing rumen-protected products, which comprises amino acid, choline chloride, glucose, urea, ammonium chloride and other important coated products for ruminants, wherein the coated products are thermally sprayed, granulated and sieved to be stable in rumen, and the obtained products are spherical particles, uniform in particle size, good in fluidity, good in solubility, high in product purity and good in quality. The coating series products can prevent nutrient substances from being damaged by rumen microorganisms, and release the nutrient substances after entering small intestines, so that the nutrient substances are absorbed by animal organisms and exert the due physiological functions of the animal organisms. (because feed pellets only pass through the meshwork and omasum when less than 1 mm, otherwise they are destroyed by ruminal grinding). The coated product prepared by the method has the following data of gastric solubility percentage and enteric solubility percentage, and is stable in rumen and stable in intestinal dissolution:
1, combined action of surfactant and hydrogenated palm oil: the product has various performances of good dispersion, corrosion prevention, sterilization and the like, can pass through rumen completely and can be directly absorbed in small intestine;
2, the fluidized bed coating machine bottom spraying system acts: coating the material, and uniformly spraying;
3, a coating material for preventing rumen from being damaged is added, so that the effect of the product which is dissolved in the stomach can be prevented from being influenced;
4, all the microcapsule particles subjected to bottom spraying and sieving can pass through a 40-80 mesh sieve to directly enter the rumen, so that the damage caused by rumination is avoided; the specific gravity of the product is between 0.9 and 1.0, and the specific gravity of rumen fluid is between 1.022 and 1.055, so that the product is suspended in the rumen fluid and smoothly passes through rumen along with rumen peristalsis.
Detailed Description
The present invention will be described in detail with reference to examples.
